The current study, which combined proteomic data from FNAB samples and plasma protein expression information from two SAT cohorts, revealed that SAT-related differentially abundant proteins were enriched in lipoprotein lipase activity, granulocyte chemotaxis, fibroblast migration, focal adhesion, bacterial infection and invasion, FcγR-mediated phagocytosis and tight junctions. This evidence concerns the gene LPL and bacterial infectious disease.
